These alerts may include information such as evacuation orders or shelter-in-place instructions. Receiving timely alerts allows people to take appropriate action, such as seeking shelter, securing property, and monitoring weather updates.

During severe weather events, staying informed and following the instructions of local authorities is paramount.

Climate Change and Charleston's Future

Climate change poses a significant threat to Charleston, SC, and understanding its potential impacts is crucial for the city’s future. The primary concerns include rising sea levels, increased frequency and intensity of extreme weather events, and changes in temperature and rainfall patterns. Rising sea levels are particularly concerning, given Charleston’s low-lying coastal geography. Even a small increase in sea level can lead to more frequent flooding, inundation of coastal areas, and erosion of beaches and shorelines. This affects residential, commercial and public infrastructure, as well as critical natural habitats.

The increased frequency and intensity of extreme weather events, such as hurricanes and heavy rainfall, are also predicted to worsen due to climate change. More intense hurricanes can lead to more destructive winds, storm surges, and flooding. Heavier rainfall can lead to increased river flooding, and damage to infrastructure and property. Changes in temperature and rainfall patterns can have indirect impacts on the environment, the local economy, and public health. This includes impacts on agriculture, tourism, and the spread of disease. These impacts can also exacerbate social inequalities.

Charleston is responding to the threat of climate change through various measures, including coastal protection projects, infrastructure improvements, and initiatives aimed at reducing greenhouse gas emissions. The city has developed a climate action plan that outlines specific goals and strategies for mitigating and adapting to climate change. Public awareness campaigns, community engagement efforts, and partnerships with local organizations are also crucial. These steps help educate residents. They also encourage collective action to tackle climate change challenges. Addressing the impacts of climate change requires collaborative efforts. This can be between local governments, residents, businesses, and other stakeholders.
